Dirty Ductwork

Over time, dust and debris can get into your heating ducts, limiting the amount of hot air you receive. Should your furnace not heat your house well enough, compared to before, you need to clean your ductwork. You could also check the airflow by placing your hand in front of the vents and feeling how much air it expels. Always hire an expert HVAC technician to check your ductwork for proper cleaning to avoid dirty ductwork.

Cracked Heat Exchanger

The heat exchanger of a furnace separates the warming flame from the air and lets your furnace function properly.
